Answer 1

Answer

The correct syntax would be $("li:contains('John'),li:contains('Mary')").css("color","red")

But I found out that if you had many cases to test, jQuery will perform very badly (especially on IE6, I know, it's old but still in use). So I decided to write my own attribute filter.

This is how to use it: $("li:mcontains('John','Mary')").css("color","red")

Code

jQuery.expr[':'].mcontains = function(obj, index, meta, stack){
    result = false;     
    theList = meta[3].split("','");

    var contents = (obj.textContent || obj.innerText || jQuery(obj).text() || '')

    for (x=0;x= 0) {
            return true;
        }
    }

    return false;
};
